  • Publication number: 20110113277
    Abstract: A processing unit is connected to another processing unit through a system bus composed of serial signal communication line and synchronization signal communication line to be able to communicate therewith. When an operation unit detects abnormal state in the processing unit, the operation unit supplies notification of detection of the abnormal state to synchronization unit. The synchronization unit transmits the received detection notification of abnormal state to the other processing unit through the synchronization signal communication line. Conversion unit receives parallel communication data from the operation unit through important signal line instead of general signal line and converts the received parallel signal into serial signal to be transmitted to the other processing unit through the serial signal communication line, thereby soundness among processing units connected to the system bus is ensured when the system bus is configured to attain serial communication.

  • Patent number: 7814224
    Abstract: An information processor disclosed herein prevents adverse impacts on higher priority processing due to extremely frequent receive processing when inbound traffic from a network is over-traffic state (under a DoS attack). The information processor attached to a network collects information about traffic state and, if it is determined that over-traffic state is present, deactivates the communication processing function without passing an interrupt request due to communication to the data processing block. In this state, the information processor continues to collect information about traffic state and, when it is determined that over-traffic state has terminated, starts to transfer an interrupt request to the data processing block and makes the communication processing function recover.

  • Patent number: 7757115
    Abstract: A feedback control device capable of continuously performing high-accuracy, stable control even in cases where any of multiple controllers for controlling a controlled system becomes incapable of control action. A controller (master controller) generates control data for stably controlling a heater by feedback control, controls the heater in accordance with the control data, and sends the control data to the other controller (slave controller). The slave controller receives the control data from the master controller but does not control the heater while the master controller is operating normally. If the master controller develops anomaly and becomes incapable of normal control action, the slave controller initiates feedback control of the heater in accordance with the control data received from the master controller immediately before the anomaly occurred, and controls the heater thereafter in accordance with control data generated thereby.

  • Patent number: 7716405
    Abstract: A computer system, being a stack bus system in which a plurality of computer modules are stacked and connected to one another and being capable of automatically matching and allocating bus resources such as clocks and interrupts, is provided. In the computer system including one system module and n peripheral modules, each peripheral module includes an interrupt selector, a clock selector, an arbitration signal selector, a resource decision unit, and a position identification unit. The position identification unit cooperates with a position configuration unit present in the system module to identify a position of the module, which includes the position identification unit, in the computer system, and autonomously decides bus resources used by the module. By allowing the interrupt selector, the clock selector, and the arbitration signal selector to select and use the decided bus resources, each peripheral module can match and configure the bus resources in the computer system.
